Move PX4 Guide source into /docs (#24490)

* Add vitepress tree * Update existing workflows so they dont trigger on changes in the docs path * Add nojekyll, package.json, LICENCE etc * Add crowdin docs upload/download scripts * Add docs flaw checker workflows * Used docs prefix for docs workflows * Crowdin obvious fixes * ci: docs move to self hosted runner runs on a beefy server for faster builds Signed-off-by: Ramon Roche <mrpollo@gmail.com> * ci: don't run build action for docs or ci changes Signed-off-by: Ramon Roche <mrpollo@gmail.com> * ci: update runners Signed-off-by: Ramon Roche <mrpollo@gmail.com> * Add docs/en * Add docs assets and scripts * Fix up editlinks to point to PX4 sources * Download just the translations that are supported * Add translation sources for zh, uk, ko * Update latest tranlsation and uorb graphs * update vitepress to latest --------- Signed-off-by: Ramon Roche <mrpollo@gmail.com> Co-authored-by: Ramon Roche <mrpollo@gmail.com>

+# Pixhawk 3 Pro (Discontinued)
+
+:::warning
+PX4 does not manufacture this (or any) autopilot.
+Contact the [manufacturer](https://store-drotek.com/) for hardware support or compliance issues.
+:::
+
+The Pixhawk<sup>&reg;</sup> 3 Pro is based on the FMUv4 hardware design (Pixracer) with some upgrades and additional features.
+The board was designed by [Drotek<sup>&reg;</sup>](https://drotek.com) and PX4.

+## 编译固件
+
+:::tip
+Most users will not need to build this firmware!
+It is pre-built and automatically installed by _QGroundControl_ when appropriate hardware is connected.
+:::
+
+To [build PX4](../dev_setup/building_px4.md) for this target:
+
+```
+make px4_fmu-v4pro_default
+```
+
+## 调试接口
+
+The board has FMU and IO debug ports as shown below.
+
+![Debug Ports](../../assets/flight_controller/pixhawk3pro/pixhawk3_pro_debug_ports.jpg)
+
+The pinouts and connector comply with the [Pixhawk Debug Mini](../debug/swd_debug.md#pixhawk-debug-mini) interface defined in the [Pixhawk Connector Standard](https://github.com/pixhawk/Pixhawk-Standards/blob/master/DS-009%20Pixhawk%20Connector%20Standard.pdf) (JST SM06B connector).
